Red Lamina Die Springs | Medium Heavy Duty

Photo of Lamina DieMax red die springRed Lamina die springs are made by Dayton Lamina and color coded white with red stripes to indicate that the springs have a medium heavy pressure rating. The brand name is DieMax.

The efficient Operating Range is 20% to 35% of the free length (L). Maximum deflection = 35%. Average life = 25%. Long life = 20%. Travel to solid is for reference only and not intended for operation. Deflection beyond the efficient Operating Range could create a safety hazard or and result in premature spring failure.

drawing of spring deflection parameters

The chart below provides the 35% deflection (F) and spring force in pounds for each medium heavy duty DieMax red die spring. Also shown is the travel to solid deflection (S) and the spring force constant (K) for each spring.

Use the following equation to calculate the spring force in pounds for a given spring and deflection; Force = K x 10 x F, where K is the force constant and F is the deflection in inches.
